Unknown file
Date updated: October 4, 2026
A file ending in .mo_ may belong to a proprietary, temporary, renamed, or otherwise unidentified file type. No reliable information is available about its internal structure or the software that created it.
The file should be identified from its original source, filename, location, or the application that supplied it. Renaming the file does not convert it to another format.
There is no specific program known to open this .mo_ file. The most reliable option is to use the software or service from which the file was obtained, or ask the file's provider which application created it.
Do not open the file by choosing a program at random. Identifying its source is necessary before a suitable application can be selected.
A .mo_ file cannot be converted reliably while its format is unidentified. Conversion requires knowing the file's internal format and using software that supports that format.
After the file has been identified, the creating application may provide an export or save-as option.
